ABSTRACT
OBJECTIVES: (1) To collect, analyze and synthetize the evidence on muscle dysmorphia diagnosis as defined by Pope et al. and (2) To discuss its appropriate nosology and inclusion as a specific category in psychiatric classificatory systems. METHOD: A systematic search in the MEDLINE, the PsycNET, the LILACS and SciELO databases and in the International Journal of Eating Disorders was conducted looking for articles published between January 1997 and October 2014 and in EMBASE database between January 1997 and August 2013. Only epidemiological and analytical studies were considered for selection. The methodological quality of included studies was assessed according to the Evidence-Based Mental Health and the National Health and Medical Research Council's guidelines. The support for inclusion of muscle dysmorphia in psychiatric classificatory systems was examined against Blashfield et al.'s criteria. RESULTS: Thirty-four articles were considered eligible out of 5136. Most of the studies were cross-sectional and enrolled small, non-clinical samples. The methodological quality of all selected papers was graded at the lowest hierarchical level due to studies' designs. Forty-one percent of the publications considered the available evidence insufficient to support the inclusion of muscle dysmorphia in any existing category of psychiatric disorders. The current literature does not fulfill Blashfield et al.'s criteria for the inclusion of muscle dysmorphia as a specific entity in psychiatric diagnostic manuals. CONCLUSION: The current evidence does not ensure the validity, clinical utility, nosological classification and inclusion of muscle dysmorphia as a new disorder in classificatory systems of mental disorders.

To conduct a systematic review of studies that evaluated quality of life (QOL) among individuals with eating disorders, to analyze the characteristics of specific QOL instruments for eating disorders. Bibliographic searches were conducted in 6 databases and manual searches in 2 journals, covering the period from January 1975 to June 2008. The search strategies provided a total of 29,537 references. Out of the 41 studies that met the inclusion criteria for this review, 5 reported on the validation process for 4 specific instruments for eating disorders. Among the 4 specific QOL instruments for eating disorders, 3 presented adequate development procedures and psychometric properties. However, further research is needed to prove the validity and applicability of these instruments. Additional validation studies are needed, especially in relation to patients who deny that they have a disorder.

This article provides a systematic review of articles on quality of life (QoL) among individuals with eating disorders. A literature search was conducted using six databases. Manual searches were also performed in two specialized journals, covering the period from January 1975 to June 2008. The search strategies identified a total of 29,537 articles. Forty-one studies met the inclusion criteria, and 36 were analyzed in the present review. Patients with eating disorders showed reduced QoL as compared to normal controls and individuals with other psychiatric disorders. The mental health component of QoL showed greater impairment than the physical component. Patients with binge eating disorders showed reduced physical and psychological QoL. We identified few studies on QoL in bulimia nervosa-only patients. QoL assessment of anorexia nervosa patients showed a modest impact on the physical domain. However, this finding should be interpreted with caution, since it may be due to an artifact in the disorder's psychopathology rather than better health status per se.

O objetivo foi fazer uma revisão sistemática dos estudos que avaliam qualidade de vida em pessoas com transtornos alimentares. Foram realizadas buscas bibliográficas em seis bases de dados e buscas manuais em duas revistas, abrangendo o período de janeiro de 1975 até junho de 2008. As estratégias de busca forneceram um total de 29.537 referências. Quarenta e um estudos preencheram os critérios de inclusão desta revisão e 36 foram analisados no presente trabalho. De modo geral, os estudos revelam prejuízos na qualidade de vida de pacientes com transtornos alimentares quando comparados a grupos normais ou outras patologias psiquiátricas. O aspecto mental da qualidade de vida mostra-se mais prejudicado. A avaliação da qualidade de vida em sujeitos com transtorno da compulsão alimentar periódica revela prejuízos nos aspectos físico e mental da qualidade de vida. Há pouca evidência e discussão para indivíduos com bulimia nervosa isoladamente. Em sujeitos com anorexia nervosa, a avaliação requer cautela, já que o aparente menor impacto físico pode ser reflexo da psicopatologia específica deste transtorno e não do funcionamento saudável.
